  • 2 tbsp Olive oil
  • 3 Large red onions, sliced
  • 2 tbsp Brown sugar
  • 1-2 tbsp Balsamic vinegar


  • Heat the oil in a large frying pan over a low heat. Add the onions and a good pinch of salt and cook very slowly for 15-20 minutes, stirring them occasionally to prevent them from catching. Don't be tempted to turn the heat up, as you don't want the onions to burn.
  • When the onions are softened and tinged golden, add the sugar and balsamic vinegar, this will start the caramelisation process. Cook the onions over low heat for a further 5-10 minutes, stirring occaisionally, until sticky and caramelised.
